One glance at the mountains around town and you'll see the importance of seafaring history for Kotor. The rambling Grgurina palace has models of pot-bellied local trader's ships, maps, period rooms recreating a merchant's office and a warship interior, Dutch and English nautical instruments and guidebooks and halls full of old weapons. There's also a display on the 1918 mutiny here on the Austrian navy's warship St. Georg. Look for the display of painted bottles, used by seamen to send desperate messages to their beloved ones back home. A Kotor secret is revealed here, as one of the rooms has a surprising view of a lush rooftop garden.
